The young father Stefan Lamm, who presented a perfect image to the outside world, killed his wife, two small children and finally himself in January 2012. He set fire to the apartment. All that remained was a suicide note that showed how meticulously Lamm planned the extended suicide. Friends and relatives were clueless. They are still shocked four years after the crime. Why would a man who was hard-working and always kind to his children wipe out his family? Should we have noticed something beforehand? The authors Katharina Gugel and Ulf Eberle researched for years until relatives were finally able and willing to talk about the crime and the trauma that followed. The parents of the murdered Yvonne are still looking for the one, valid reason for the crime. They found out that Stefan Lamm was 30,000 euros in debt. But is that a reason for such a desperate act? He would have gotten help. Yvonne's best friend Jenny noticed that Stefan Lamm always wanted to be the best, always perfect. He even renovated in a suit. Should she have noticed something, said something? The person who blames himself most is friend André, who noticed in the last few months before the murder how much Stefan had changed but was unable to talk about problems. The tragedy in Langenfeld is not an isolated case: the family facade is intact, fractures and problems are covered up with all possible force until the crime seems inevitable for the perpetrator. Two psychologists are responsible for classifying the individual case. Heidi Kastner from the University of Linz - a luminary in the assessment of perpetrators - analyzed Stefan Lamm's long farewell letter. She recognizes a narcissistic disorder - often the cause of an extended suicide. Erika Jungbluth treats many narcissistically disturbed patients in her practice. They hardly stand out in a society in which self-optimization and perfectionism are considered desirable. ????
